Scroll the options with Start Stop and Light Lock and press Next to select a POD or heart rate sensor to pair.

Hold your Suunto Ambit3 Sport close to the device you are pairing and wait for Suunto Ambit3 Sportto notify that pairing was successful.
If the pairing fails, press Start Stop to retry, or Light Lock to return to the pairing setting.

If you pair a power POD, you may need to define additional parameters in your Suunto Ambit3 Sport. These include, but are not limited to:

Left crank or Right crank

Left pedal or Right pedal

Rear dropout

Chainstay

Rear wheel or Rear hub

Using foot POD

When using a foot POD, the POD is auto calibrated by GPS at short intervals during exercise. However, the foot POD always remains the source of speed and distance when it is paired and active for the given sport mode.

Foot POD auto calibration is on by default. It can be turned off in the sport mode options menu under Activate, if the foot POD is paired and is used for the selected sport mode.

For more accurate speed and distance measurements, you can manually calibrate the foot POD. Perform the calibration on an accurately measured distance, for instance, on a 400 meter running track.

To calibrate foot POD with Suunto Ambit3 Sport:

Attach foot POD to your shoe. For more information, see user guide for the foot POD you are using.

Choose a sport mode (for example Running) in the start menu.

Start running at your usual pace. When you cross the starting line, press Start Stop to start the recording.

Run a distance of 800–1000 meters (about 0.500–0.700 miles) at your usual pace (for example two laps on a 400 meter track).

Press Start Stop when you reach the finish line to pause the recording.

Press Back Lap to stop recording. After stopping the exercise, save the log by pressing Start Stop. If you do not want to save the log, press Light Lock.
Scroll with Next through summary views, until you reach the distance summary. Adjust the distance shown on the display to the actual distance you ran with Start Stop and Light Lock. Confirm with Next.

Confirm the POD calibration by pressing Start Stop. Your foot POD has now been calibrated.

NOTE:

If the foot POD connection was unstable during the calibration exercise, you might not be able to adjust the distance in the distance summary. Make sure that foot POD is attached properly according to instructions and try again.

If you are running without a foot POD, you can still get running cadence from the your wrist. Running cadence measured from wrist is used together with FusedSpeed (see FusedSpeed) and is always on for specific sport modes including running, trail running, treadmill, orienteering, and track and field.

If a foot POD is found at start of an exercise, running cadence measured from wrist is overwritten by foot POD cadence.

Calibrating power PODs and slope

Suunto Ambit3 Sport automatically calibrates your power POD when it finds the POD. You can also calibrate the power POD manually at any time during an exercise.

To manually calibrate a power POD:

While you are in a sport mode, keep Next pressed to access the options menu.

Stop pedaling and lift your feet off the pedals.

Scroll to Calibrate Power POD with Light Lock and select with Next.

Suunto Ambit3 Sport starts calibrating the POD and indicates if the calibration succeeded or failed. The bottom row of the display shows the current frequency used with the power POD. The previous frequency is shown in parentheses.

If your power POD has an auto zero feature, you can turn this on/off through your Suunto Ambit3 Sport.

To set auto zero on/off:

After the calibration is completed, press Start Stop.

Set auto zero On/Off with Light Lock and accept with Next.

Wait until the setting is completed.

Repeat procedure if setting fails or power POD is lost.

You can calibrate the slope for power PODs that use Crank Torque Frequency (CTF).

To calibrate the slope:

After the power POD calibration is complete, press Start Stop.

Set the correct value according to your power POD manual with Light Lock and accept with Next.
